A production-grade content dashboard that orchestrates multiple external data streams (News, Media, User Analytics) into a unified, high-performance interface. The platform focuses on modularity, state persistence, and robust error handling to ensure a seamless user experience.
- Frontend Framework: Next.js 15 (App Router) for Server-Side Rendering (SSR) and optimized hydration.
- State Orchestration: Redux Toolkit for complex state management and local storage persistence for zero-latency user session recovery.
- Testing Strategy:
- Unit: Jest for core utility logic (debouncing, data parsing).
- Integration: React Testing Library for component lifecycle and state interaction validation.
- E2E: Cypress for critical path user journey testing (Search -> Filter -> Favorite).
- Cross-Domain Data Orchestration: Unified API fetching logic to handle disparate data structures from various providers.
- Performance Optimization: Implemented debounced search and memoized component rendering to prevent unnecessary re-renders during high-frequency user input.
- Dynamic UI/UX: Leveraged Framer Motion for hardware-accelerated animations and React DnD for intuitive, drag-and-drop content reordering.
- Resilient Error Handling: Integrated proxy-based API calls to mitigate CORS issues and provide fallback states for failed requests.
- Language: TypeScript (96.3% of codebase)
- Framework: Next.js, React
- Styling: Tailwind CSS
- Persistence: Redux, LocalStorage
- QA/CI: Jest, Cypress, ESLint
- Code Quality: 100% Type-safe implementation with TypeScript.
- Test Coverage: Comprehensive coverage across unit, integration, and end-to-end suites.
- Accessibility: Optimized for Lighthouse accessibility standards.
